Usage: config-be [-c|--copy] [-b|--be] [-n|--nocache] [-f|--full]

config-be runs the normal configure script, creates the Makefiles
and then replaces a few of the created files with its own version.
The latter is necessary since the current edition of the autoconf suite
does not generate fully functional Makefiles.

The following options are available:

  --copy:    the files which need to be modified after the configure run
             are copied verbatim from be/ instead of patching the files
             created by configure.
          
  --be:      the src/Makefile is able to cross-compile prcs.

  --nocache: Remove config.cache if existing.

  --full:    Run autoconf first to recreate the configure script.
             You need the full auto* suite for this.
